UNITED STATES TIMER-COVER DEVICE.

Specification of Letters Patent.

Patented Apr. 19, 1921.

Application filed February 10, 1920. Serial No. 357,675.

T 0 all whom it may concern:

Be it known that I, Jens Jnsrnnsnu, a citizen of the United States, and a resident of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Timer-Cover Bevice, of which the following is a specification.

The object of my invention is to provide a timer cover device made of a single piece of resilient material, and so designed that it may be easily and readily placed over the ordinary timer of an automobile.

Still a further object is to provide a timer cover adapted to be yieldingly held in position on an automobile, and to prevent oil from coming in contact with the wires from the timer. I v

Still a further object is to provide a timer cover preferably made of resilient material,

whereby it may be sprung to various sizes, in order to accommodate any variations of the parts of the engine casing.

Still a further object is to provide a timer cover member adapted to be received against r the cover an engine casing, and designed to beheld against movement by parts of the engine casing, and an arm extended over a part of member for yieldingly holding it against movement in one direction.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim and illustrated in the accompanying drawings, in which:

Figure 1 shows afront elevation of an automobile engine, with my improved timer cover placed thereon.

Fig. 2 shows a central. sectional view taken on line 2-2 of Fig. 1. I

Fig. 3 shows a sectional view taken through. a portion of the engine casing, showing a plan elevation of my device; and

Fig. 4 shows a detail view of part of my timer cover, parts being broken away to better illustrate the construction.

In the accompanying drawings, 1 have used the reference numeral 10 to indicate an ordinary engine or crank case, which is provided with the crank shaft 11 and an engine block 12.

An oil cup 14 is provided, which extends into the crank case 10. Extending through the oil cup 14 is a bolt 15. Extending tofore referred to.

through the crank case 10 is the cam shaft 16 upon which is mounted the timer actuating mechanism. timer usedupon Ford cars.

In order to hold the ordinary timer against the engine casing 10, an arm 18,

which is provided with 2. lug 19, extends.

into a recess formed in the timer 17 The free end of the arm 18 is provided with an opening through which the bolt 15 extends.

The engine; or crank case 10 isprovided with a series of bolts 20, which extend close to the timer 17.

It will be understood that the ordinary timer is provided with a spark control lever 21, and wires 22, which lead from the timer 17 to the coil box.

It will be understood that these wires become covered with oil and are subject to be torn by the moving parts of the automobile engine; for example the belt or fly wheel coming in contact with the wires 22 would cause them to be broken, and thus injure the ignition system of the automobile.

. In order to overcome this difiiculty, I have provided a timer cover 23, preferably made of a single piece of resilient material.

The timer cover 23 is provided with a. recess 24. The cover 23 is ofsuch size that it will be received between the various bolts 20 of the engine casing 10. The cover member 23 is provided with sides 25. The sides 25 rest against the bolts 20. i

It will be understood that when the cover is placed over the timer 17 and the sides 25 of the cover are yieldingly forced in between the various bolts 20, it will thus be held in position.

I have also provided an arm 26, which is of similar construction to the arm 18, here- The arm 26 is provided with a lug 27, which is received in the recess 24 of the timer cover 23. The free end of the arm 26 is provided with an opening through which the bolt 15 also extends.

It will be seen that when my cover member 23 is placed between the bolts 20 and then the arm 26 is placed in such position that the lug 27 will be received in the recess 24, and when the bolt 15 is tightened, then the cover member 23 will be absolutely held against any movement in any direction whatsoever.

Extending from one of the sides of the cover 23 are the flanges 27 and 28. The flange 27 is directly below the oil cup 14,

17 shows the ordinary and is designed to overlap the wires 22 and thus prevent any oil, which may drip from the oil cup 14 from coming directly in contact with the wires 22 and thus into the timer 17.

It will be understood that if any oil does come in contact with the wires 22, it will be far enough away from the timer, so that it could not possibly run into the contacts of the timer.

The flange 28 is curved so that none of the wires will come into contact with the sharpened edge, and thus have their insulation torn off.

Between the flanges 27 and 28 an opening 29 is vformed. It is through this opening that the wires 22 lead from the timer 17 to the coil box.

In order that the spark control lever 21 may be operatively connected with the timer 17, I have provided the slot 80 near the upper end'of the timer cover 28. The slot 30 is provided with an opening 31 through which the control lever is extended, when the timer cover is placed in operative position.

One of the advantages of my device is that I am able to fully protect the timer and the wires leading therefrom, so that no oil or other foreign matter comes in contact with them.- I I Another advantage is that by leading the wires 22 through the opening 29 of the timer cover, all possibility of the wires 22 coming in contact with the fan wheel or belt from the fan wheel, and thus having their insulation removed and being rendered inoperative is avoided.

Another advantage of my device is the method in which it is fastened to the engine case. By making the timer cover of resilient materlal, any variation in the distance between the various bolts 20 will readily and easily be taken care of, the parts of the timer cover being capable of being sprung to various positions or sizes in order to accommodate any irregularities in the bolts 20. The arm 26 will prevent the timer cover from movement in one direction.

It will thus be seen that the arm 26 and the bolts 20 hold the timer cover 23 in positive position relative to the timer. A great amount of ignition trouble is caused by the wires from the timer becoming oily and having the insulation removed therefrom and coming in contact with each other.

It will be seen that with my device, I am able to practically eliminate the ignition trouble of this nature.

Some changes may be made in the construction and arrangement of the various parts of my improved device without departing from the essential features and purposes of my invention, and it is my intention to cover by my claim any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:

In combination with an engine housing having a plurality of bolts therein and a timer thereon, a cover member of a single piece of resilient material formed to have a body portion to extend over the timer and a flange formed from the edge of said body portion, said flange being designed to rest against the engine housing and have its edge against the bolts of said engine housing, the parts being so arranged'that said cover member may be sprung to position where it will be received between said bolts and when released it will be yieldingly held over said timer by said bolts.
